Theapparatus and 3, inclu'desa frainef'membermade up, of

clearly shown in Figuref, yandi held linjialined bridging member 14conveniently formed integrally with the rails 12 and 13; the bridgingmember 14 is provided with an intermediate portion 15 curved as showninFigure 2 to provide a suitable finger rest.

The rails 12 and 13 are U-shaped in crosssection, as is shown in'Figure5; this crosssection might be given the rails by pressing or rollingsheet. metal into this form or by cutting into a solid bar appropriatelengthwise-extending slots to form p appropriate guiding ways. The siderail 12 (Figure 2) is toothed along its upper inner edge to form a rackindicated at 16. Slidablymounted in the facing slotsor guideways in therails 12 and 13 is the bottom cutter plate 17 provided Y with teeth17Ialong its upper edge, as seen in Figures 2 and 4; this cutter plate 17is flanged as at 18 and 19 (see Figure) so that the fiange portions 18and 19 ride ywithin the guideways of the rails 12 and 13 and so that theplane of the cutter plate 17 is adjacent to or substantially underneaththe lower edges of the rails 12 and 13, as seen in Figure 5.superimposed upon the cutter plate 17 is an upper and coacting cutterplate 2O provided with teeth 20a along its upper vedge and substantiallyabove the teeth 17 a of the lower cutter plate 17. The cutter plate 2Ois of less width than the lower cutter plate 17 asl will be clear` fromFigures 2,14 and 5, and is slotted as at 21 and 22; through these slots21 and 22 are passed the studs y23 and 24 respectively, the studs beingappropriately secured` to the lower cutter plate 17 and beingconveniently threaded thereinto. The

l .studs 23 and-24 holdthe. cutter plate 2O in coacting relation to thecutter plate 17 while the slots 21 and 22 per-mit lateral movement ofthe upper cutter plate .'20 relative Ato the lower cutter plate 17, sothat the overlapping teeth of these two plates can coact in the cuttingor severing of hair.

The lower cutter plate `17 has Y rigidly v'mounted therein a stud shaft25 .(see particu- 'larly Figure 5), the studshaft extending upwardlythrough a horizontally extending slot 526 in the cutter plate 20, theslot 26 perfree reciprocating movement ofthe kcutter plate 2O and thestud shaft 25 assisting mitting in guiding the cutter plate 20 relativeto the cutter plate 17. Rotatably mounted upon the stud shaft 25 is apinion 27 meshing and coacting with the rack 16 in the side rail 12; thepinion 27 has superimposed upon it and connected with it a relativelylarge gear .28 which is adapted to mesh with andl drive a smaller gear29 (and hence at a greater speed than that of the pinion 27 The gear 29is fixed to a shaft 30 the upper end of which is rotatably vsupported ina suitable bearing provided in the casing v31 to be more clearlyhereinafter described andthe lower end of which `is rotatably supportedin the lower cutter secured thereto 17 is moved alond the uideways inthe side rails 12 and 13 it carries the upper cutter Aplat'e'2() with itand at the same time the engagement'between the rack 16 and pinion 21effect a relatively high speed of rotation of the eccentric 32 and thelatter thus effects a relatively high Y speed of reciprocating movementofthe ycutter plate 2O relative to the lowercutter plate 17 I The cutterplate 2Ov is cutaway yasfatv35 (see Figure 4) s o as to expose anappropriate portion of the lower cutter plate 17; upon this exposedportion of the latter there is secured, as by means of the screws 34,the casing member 3.1 hereinabove mentioned.` The casing member 31ispreferably made of sheet metal, extends over the driving mechanism toprovide suitable supports'for the upper ends of the shafts 25 and l30and, moreover, is flanged so as to overlap the driving mechanism andsubstantially encase the latter. Moreover, the screws 34 permit theycasing 31 to be readily detached whereupon the driving mechanism may bequickly disassembled for repair or replacement.

Y inger piece'36 preferably of a generally tubular shape, as is Vclearlyvshown in Figures 2, 3 and 6, and otherwise appropriately shaped andcurvedto permit the ready insertion therein yof afinger, preferably thethumb. The length of theapparatus is preferably such that, as viewed inFigures 2 Vand 3y for example, the thumb of one hand may be insertedinto thetubular finger piece 36 and a finger of the same hand placedagainst the fingerpiece 15, the drawing of the thumb toward the fingereffecting an upward movement of theY apparatus along the guideways 'ofthe side rails 12 and13,pwith the driving action ofthe cutter orclipping mechanism as above described. Thelower ends of the side rails12 andV 13 are' securely held in spaced relationbymeans ofa cross-bar 37by screws '38 and' 39, this cross-bar 37 beingsecuredin position afterthe cutting mechanism hasmbeen assembled relative withtheside rails 12and 13 and Vacting to hold the parts in, such assembled relation. f

Coacting with the cutter plates 17 20 is a comle'40 preferablymade ofrelatively thin sheet metal and extending underneath the cutter plate 17this-comb 40 has thefor'ward portion of its teeth curved, as indicatedat 402I in Figure 3,'in a direction toward and around the coacting teethof the two cutter plates. 'The combV 40 is pivotally mounted bolt 50 isa spring 51.

as at 41 to a platemember 42wliich is detachably secured as by screws 43and 44 to the lower upstanding portions? of the casing 3l and thethumb'piece 36,v the plate member 42 thus extending against and alongthe lower edge of the cutter plate 17. The sheet metal of the comb isbent and bifurcated at 40b so as `to extend into and about the annulargroove. 45 on the shank of a thumb screw 46, the latter being threadedinto the plate member 42. Thus'byadjusting the thumb screw 46 relativeto the plate 42 the comb 40 may be adjustably positioned about the axisof its pivot 41 and thus the spacing of the comb 40 from the cutterplates (see Figure 3) maybe predetermined at will. j

The upper end of the `bridge member 14 with two upwardas at 47a and 48arespectively to permit the arms 47 and 48 to yield. Received between theupper ends of the arms 47 and 48 is a member 49 held in place by meansof a bolt 50 passing through the arms 47 and v48 as well as through themember 49, the adjacent contacting faces ofthe arm 47 and memberl 49beingtoothed as indicated in Figure 2, while interposed'between the nut50FL ofthe The spring 51 is of sufticient strength to insure that themember 49 is gripped between the yieldable arms 47 and 48 and yet mayyield to permit the member 49 to be manually adjusted or swung out asubstantial extent.

f with a knurled tions the auxiliary band 60 wise secured at its ends toabout the axis of the bolt 50, the interengaging teeth acting to holdthe member 49 into whatever position it is thus adjusted. The member 49(see Figure 3) is provided with a transversely extending and preferablyintegrally formed member 52 preferably of tubular shape andV interiorlythreaded through- The threaded member 52 is adapted to receive thethreaded end of a member 53, the latter being provided wheel 54 so thatthe member 53 can be manually rotated and provided further with a ball55 adapted to be received Within the socket portion 56 of a sheet metalmember 57 so as to 'form substantially a ball and socket c 57 moreclearly shown in'Figures 2 and 3, is provided with a pair of slots 58and 59 through which a band 60, preferably of leathl er, is adapted tobe passed. The band 6 0 is superimposed upon the main supporting orattaching band 1l but is of lesser width than the latter. Y

The auxiliary band 60 isa suicient length to extend, when the bandmember 11 is applied to the head substantially as shown in Figure 1,from substantially one side of the head, then the other side of thehead. At theseside poris sewed'or otherthe main bandll,

'in Figure l. The

Y bers 53-52, the hand wheel f will take'a position for joint. The sheetmetal memberY .the two cutter hand is thereupon the temple onaround theback -1 of the head to substantially the temple onasis'indicated at 61in VFigure 1:. The plate member 57 maytthus Vbe adjusted along theauxiliary band'60 when the apparatus' is inv operative position,asshownin Figure l', but it is to be noted that anyIsliding-adjustmentgiven the plate member 57 relative to the auxiliary band 60 may beaccomplished'without causing the plate member 57 to interfere with,catch, or disarrange'the hair, since the main band 11 is interposedbetween the plate member 57 and the'hair.

. In the vuse of the apparatus the hair is iirst combed or brusheddownwardly and theband member 1l with the apparatus attached thereto ashereinabove described is then attached to the head substantially asshown band` 1l is lpreferably Vso positioned and adjusted that thecutting mechanism, when .positioned at Vthe lower ends ofzthe Vsiderails 12-13 rests well beneath the lower or extreme growth of hair,while a final adjustment to bring the cutting mechanism, when thus atthe lowerends lof the side rails 12-13, into the desired lowermostposition, may beachieved by increasing vupwardly along the rails 12-13.vMoreover, the upper ends of the si'de rails 12-13may be 'z adjustablypositioned toward or away from the back of the head as by lengthening orshortening the linkage formed by the mem- 54 making possible a rapidachievement of The adj usting'screw 46 see particularly Fgure 3) may beadjusted so that the comb 40 example substantially flush against theunderside of the lower cutting plate 16, `but the ofthe teeth of thecomb 40 will be seen to curve around the relatively sharp edges ofplates and thus prevent the cutter teeth or the edges of the latter fromdigging into the scalp. 'The thumb of oneplaced in thethumb piece 36 anda linger of the same hand then placed upon the linger piece 15.Thereupon the thumb is brought toward the Vfinger and there isthus-effected an upward cuttingmechanism' along the curved side rails1-2-13, the driving mechanism hereinabove described causing anappropriately rapid reciprocation of the cutter plate 2O` relative tothe cutter plate17 toeect a cutthis adjustment. f L

Upper curved, ends 40@ movement of the gear 29. The hub is cut away asting of the hair as this movement of translation is brought about.During this upward movement of the cutting mechanism the comb 40 acts`to guidethe hair into the coacting teeth' of the cutter plates and actsin eect to substantially stand the hair up on end and thus bring thelatter into the desired coacting relation to the cutter teeth. Theselatter actions may be achieved without the use of the` comb 40, theteeth of the cutter plates themselves being relied upon to achieve thisaction. However, I prefer to use the comb 4() due to certain otheradvantages achievable thereby. l

Moreover, as the cutting mechanism moves upwardly along the guiderails12-13, it is brought progressively farther away from the scalp, aswillbe clear from Figure l, so that the hairis cut with nicety anduniformity to gradually increasing lengths, permitting it to mergegradually into the length of the hair near the upper portions of thehead where it need not be cut. Also, it is to be noted that the cuttingmechanism is brought into action very close to the skin at the backofthe neck so that the desired edect at those portions may befdependablyachieved. Y After the cutting mechanism has been moved upwardlypreferably throughout the entire length of the guide rails 12-13, theclose proximity of the thumb piece 36 to the finger piece l5 makespossible the secure gripping and manual control of the entire apparatus,whereupon it is given a slightsideways movement along the supportingbands 11-60 and preferably throughout a distance somewhat less than' thewidth of the cutter plates so that upon the next upward traversingmovement ofthe mechanism the latter will operate throughout a regionimmediately adj acentthat region just cut. It will be understood, ofcourse, that this sideways movement may be otherwise achieved than byholding the apparatus by means of the mem-' bers 36 and 15.

The member 36 is preferably tubular so that a downward movement of thethumb will be effective to move the cutting mechanism downwardly alongthe guide rails l2-.-13 and bring thecutting mechanism to the lowermostends Vof thel guide rails and in readiness-for. a succeeding cuttingtraverse.

'During the downward movement of the cutting mechanism and in order tofacilitate this downward movement, I prefer not toreciprocate the cutterplate 20 relative to the cutter plate 17. This I prefer to achieve byconnectingthe gear 29 (Figure 5) to the shaft 30 (which carries theeccentric 32) by means of a ratchet mechanism which may conveniently beof the form shown on a 'large scale in Figure 7. YThe latter figureshows in section the shaft 30 and the hub ofthe at'29a in `tion'29agradually tapering `be seen thatthe apparatus is ymeans `direction alongwhich-the mechanism is to lbe away portion 29a a sulficientspace toreceive loosely a band or roller `62, the cut away portoward itsotherendinl a direction towardthe shaft 30. As the gear 29 is thus rotated inclockwise direction as seen in both Figures 2 and 7, in response to itsactuation by the rack land intermediate mechanism, the ball or roller 62is wedged between the hub ofthe gear 29 and the shaft 30 and the latteris thus brought into rotation but as the cutting mechanism is moveddownwardly along the guide rails 12-13 the gear 29 will be rotated incounter-clockwise direction and the ball or rollerk 62 released from itswedging action so that the gear 29 may freely rotate relative to theshaft 30, the latter thus remaining stationary.

During thev cutting action of the mechanism the casing 31 effectivelyencloses the driving mechanism and protects the latter against the cuthair. Also, I may adjust the comb 4() by means of the thumb screw 46(see Figure 3) so as to interpose between the scalp and the cutters anydesired distance.t

and thus predetermine the minimum length to which the hair will be cut.f This adjustmentI find particularly advantageous in cutting the hair toeither side of the ears where it is oftimes, desired to avoid croppingthe ,j

hair too closely to the scalp. j

It will thus Vbe seen that there has been provided in this invention anapparatus in.
